Quality of Earnings Explained: What Buyers Really Test in M&A
QoE is more than an EBITDA bridge. It is the buyer's test of whether reported earnings will survive the first year after close.
A Quality of Earnings analysis answers one question: will these earnings repeat after we own the business? Sellers present adjusted EBITDA. Buyers stress-test every add-back, accounting policy, and revenue recognition assumption behind that number.
What QoE covers
At its core, QoE reconciles reported EBITDA to a normalized view the buyer will underwrite. That usually means:
- Trailing twelve months (TTM) or last fiscal year as the base period
- Identification of non-recurring income and expense
- Owner and related-party compensation normalization
- Run-rate adjustments for contracts won or lost near the measurement date
- Working capital and cash flow quality checks that support the earnings story
QoE is not an audit. It is a transaction-focused analytics exercise, often faster and more judgment-driven, with conclusions framed for purchase agreement negotiations.
The EBITDA bridge
The bridge is the working document. A typical structure:
- Reported EBITDA from the financials
- Add-backs proposed by the seller (owner comp, one-time costs, etc.)
- Haircuts proposed by the buyer (unsustainable savings, aggressive run-rate)
- Normalized EBITDA the buyer will use for valuation and covenants
Each line should tie to evidence: GL detail, invoices, payroll registers, or contracts. Bridges that cannot be sourced become negotiation leverage.
Seller vs buyer perspective
Sellers want the highest defensible normalized EBITDA because valuation often follows a multiple. Buyers want conservatism, especially on run-rate add-backs, pro forma synergies, and capitalization vs expense decisions.
Common friction points include:
- Owner compensation: What is market rate for the replacement CEO?
- Related-party rent: Will occupancy cost change at arm's length?
- Customer concentration: Is a large contract truly recurring?
- Capitalized costs: Were software or R&D costs expensed appropriately?
How diligence teams deliver QoE
Experienced teams pair structured analytics with management interviews and document validation. Request lists go out early. Trial balances and GL are mapped to a standard chart. Adjustments are logged with status (proposed, accepted, rejected) and linked evidence.
The output is a QoE report or memo, often with an Excel bridge, issue log, and management questions, that feeds the purchase agreement, lender package, and post-close integration plan.
Takeaway
QoE is the financial truth test in M&A. The teams that win are not the ones with the prettiest deck. They are the ones with sourced bridges, clear assumptions, and fast iteration when new documents arrive.
